[1] POWER STEERING ASSEMBLY

(1) Construction of Power Steering Assembly

The power steering assembly is mainly composed of
an input shaft (1), output shaft (in the gear case side) (5),
torsion bar (2) for connecting these shafts, torque sensor
(3) for detecting the twisting of the torsion bar, and motor
(4) for generating assisting power. A stopper is provided
for the input shaft (1) and output shaft (5) in order to
prevent twisting beyond setting at the time of steering.
If the torsion bar (2) should be damaged, steering
can be performed with the steering wheel attached as it
is.
